Looking for some direction on this. I'm building a protools 105 bender clone. I had some 1/2" drops around, so we cut out arms.
I'm trying to determine a cylinder to use on it. I know all about using the HF air over hydro, but I'm looking to go full hydro and use the pump I have for my small car lift to run it. Protools sells a SPX ram for them, but they are silly expensive. This is the one that protools sells for the conversion.
I'm looking at buying one of these
Am I missing something or will that cheap one work fine? I know the SPX one has a spring to retract it, which I can add externally. Is it worth doing all this, or should I just use the HF ram? I'm not going to be doing a ton of tube work, but I am building at least one cage in the next year.
